Abstract
A method includes collecting trace data associated with a plurality of device testers. Tester health metrics are generated for each of the device testers. The tester health metrics are analyzed to identify a selected tester health metric that diverges from the plurality of tester health metrics. A corrective action is initiated for the tester associated with the selected tester health metric. A method includes collecting trace data associated with a plurality of device testers. The trace data for each of the device testers is compared to a reference trace data set to generate tester health metrics for each of the device testers based on the difference therebetween. The tester health metrics are analyzed to identify a selected tester health metric that diverges from the plurality of tester health metrics. A corrective action is initiated for the tester associated with the selected tester health metric.
